  • Short name: BITOFF
  • Long name: Reset Bit

Memory layout

0x83 D / S Dest Bit

Arguments

  • const Bit[4] D: Destination bank.
  • const Bit[4] S: Source bank.
  • const UByte Dest: Destination address.
  • const UByte Bit: The number of the bit to turn off.

Description

Sets the nth bit in the "Dest" location, where n is a number between 0-7 supplied in "Bit". A value of zero in "Bit" will reset the least significant bit. If the Source Bank is 0 then the bit to be set is taken from "Bit". If the Source Bank is an 8 bit bank, then the “Bit” is the address in that bank where the operand is.
